2 years ago From the top of my head... Physically and cheaply there's no way to do that, except for hanging on your side a configured plc. Then you physically get access to this physical plc. Further you will able to read coupler's memory areas. Virtually, you can also hang on your side virtial plc(by means of plcsim), then get access to this virtual plc. Further you will able to read coupler's memory areas.

2 years ago From what I'm reading PN-PN couplers don't offer datablock access at all. Also, they're using Profinet as communication protocol (hence the PN in the name), this library doesn't support Profinet in any way. I think you're out of luck unless you get direct access to the PLC.

Hey there,
does anybody has experiences with a pn-pn-coupler and know how to handle it with s7netplus?
In my case, I have a SINUMERIK NCU 710 (integrated S7300) connected to a pn-pn-coupler (Siemens PN-PN-Koppler 6ES7 158-3ad10-0XA0 V4.2). If I connect my laptop directly to the PLC then I can open a connection. But unfortunately the network comprises a coupler. How do I get the data blocks from the coupler?
Does anyone have a tip or suggested solution for this hardware setup?
btw I am a student and I have not much programming experience.
